摘要： PROBLEM TO BE SOLVED: To provide a joint structure for a segment with high joint strength, which is simply, easily and automatically assembled without using bolts and nuts. SOLUTION: Joint plates 3 are provided on the joint faces of both segments 1, respectively, and through-holes 3a are provided corresponding to the joint plates 3, respectively. In one through-hole 3a, a connection fitting 7 having a head 7a and a connection 7b passing through the through-hole 3a from the inside to the outside is installed to form a male joint. Inside the other through- hole 3a, a fitting groove 8 to fit the connection 7b of the connection fitting 7 in series to the through-hole 3a and a wedge fitting hole 10 to fit a wedge fitting 9 from the hollow side of the segment 1 to the direction of its thickness are provided crossing each other to form a female joint. The connection fitting 7 for the male joint has a wedge through-hole 7c at the end, whereby the wedge fitting 9 fitted from the hollow side of the segment 1 into the wedge fitting hole 10 in the female joint can pass through the wedge insert hole 7c in the connection fitting 7 in the condition that the connection fitting 7 is fitted in the fitting groove in the female joint.

摘要： PROBLEM TO BE SOLVED: To form a joint between rings in an instant not by a normal bolt fastening system but by using jack thrust at the time of excavation of a shield machine in order to cope with automation and rapid construction. SOLUTION: A male joint 11 protruded from the joint face of a segment is fitted into a female joint 21 provided inside the joint face of an adjacent segment, to joint both segments to each other. The male joint 11 is formed of a steel bar body with a groove 12 in the circumferential direction of the tip part, and the tip part is machined in tapered shape. The female joint 21 is formed of a cylindrical body made of steel and having a plurality of axial slits 23, and an engaging protrusion 22 is formed at the inner surface. When the male joint 11 is pushed into the female joint 21, the male joint 21 is radially enlarged because of the presence of the slits 23. In the completely pushed-in state of the male joint 11, the engaging protrusion 22 of the female joint 21 is engaged with the groove 12 of the male joint 11 so as to prevent slip-off of the male joint 11.

摘要： PURPOSE:To reduce a cycle time by smoothly braking even a capsule having heavy weight and a wide range of approach speeds through a relatively simple mechanism and at a relatively short distance, and enabling the capsule to be transferred to the next process. CONSTITUTION:A capsule deceleration device such as a torque converter 4 and a drive device such as a motor 5 are connected via a reducer 3 to rubber tiers 1A and 1B rotatably supported and so laid as to be capable of being pressed to the side of a capsule C. Also, the tires 1A and 1B are kept rotating at a speed less than capsule approach speed on the operation of the motor 5. When the capsule C approaches, the speed of the tires 1A and 1B increases due to a frictional force, and the torque converter 4 at the side of the tiers 1A and 1B gives a slip relative to the drive side, thereby absorbing an excess of torque. As a result, the capsule C is decelerated and braked.

摘要： PROBLEM TO BE SOLVED: To provide a revetment structure requiring a smaller bank main body than do structures of the prior art and being excellent in profitability, constructibility, and safety. SOLUTION: A flexible sheet serving as an extension member 3 is mounted on the bottom surface of an L-wall 1 constituting a bank main body. The extension member 3 further extends backward from the rear end of the rear base 1a of the L-wall 1, and the weight of earth filling on the extension member 3 can be expected as the sliding-resisting weight of a bank. A three-dimensional grid-shaped anchor 5 comprising a horizontal member 5a, a column member 5b, and a steel plate 6 mounted on the back thereof is connected behind the L-wall 1 via a joint 7. The rolling resistance of the bank main body can be increased by the dragging resistance of the horizontal member 5a and the column member 5 which constitute the three-dimensional grid-shaped anchor 5 and that of back filling and by earth pressure resistance working on the steel plate 6 located on the back of the three-dimensional grid.

摘要： PURPOSE:To improve cut-off properties by preventing movement and deformation by wave power. CONSTITUTION:A cell 1 body is formed by unifying a cylindrical sidewall 2 made of a steel sheet and floor blocks 3 made of reinforced concrete in required thickness. The floor blocks 3 mounted in fixed height on the inside of the sidewall 2 improve the rigidity of a cell 1 while giving weight for resisting wave power. Pipes 6 for placing concrete are penetrated to the floor blocks 3, and concrete 7 is placed on the lower sides of the floor blocks through the pipes 6. The upper sections of the floor blocks 3 are filled with soil and sand, etc., having proper gain size as a fill material 4. Upper construction 9 such as cast-in- place concrete is carried out to the upper section of the fill material 4 filled as a cover. Accordingly, the rear of a cell structure constructed is filled up with reclaiming soil 14.
